UNITED STATES PATENT oFFlcE-Q ARTHUR O. HUBBARD, OF MINNEAPOLIS, MINNESOTA; NELLIE H. HUBBARD, EXECU-- TRIX OF SAID ARTHUR O. HUBBARD,

DECEASED, ASSIGNOR TO BUFFER-HUBBARD MANUFACTURING COMPANY, OF MINNEAPOLIS, MINNESOTA, A CORPORATION OF MINNESOTA.

Application filed May 13, 1921.

To all whom. it may concern:

Be it known that I, ARTHUR O. HUBBARD, a citizen of the United States, resident of Minneapolis, county of Hennepin, State of Minnesota. have invented certain new .and useful Improvements in 'Wringers, of which the following is a specification.

The object of my invention is to provide a wringer framev of compact, strong and durable construction, which can be easily set up and taken apart and is so braced that it will not be racked or twisted by the strains and stresses to which the wringer frame is ordinarily subjected.

Other objects of the invention will appear from the following detailed description.

The invention consists generally in Various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure 1 is a front elevation of a wringer frame embodying my invention,

Figure 2 is a vertical sectional view of the same,

Figure 3 is a transverse sectional view,

Figure 4 is a side elevation of one end of the wringer frame, showing the manner of mounting it in the housing of the driving mechanism.

In the drawing, 2 represents a casing or housing wherein the driving shaft and gears for the wringer are mounted and 3 is a lever which controls the operation of the driving mechanism. 4 is-a housing secured to the adjacent end rail 5 of the Wringer frame and having ears 6 attached to the upper part of the housing 2 by suitable means, such as pivot bolts 7 The lower portion of the housing 4 has ears 8 and a rod 9 engages a bolt 10 that is mounted in the ears 8 and asses through a bracket 11 on the lower wall of the housing 2 and is secured therein by suitable means, such as lock nuts 12. When these nuts are tightened, the frame of the wringer will be securely clamped to the housing 2.

A drive shaft 13 projects through the wall,

Serial No. 469,123.

shaft of the upper roll has a drivin connection with a pinion 21 on the shaft of the lower roll and thus both rolls are positively driven.

The end rails 5 of the wrin er frame are formed in pairs with spaces24laetween them and blocks 25 closing the spaces at the lower portion of the frame. Bearing blocks 26 and 27 are provided in the spaces between the rails 5 of each pair in which the shafts of the upper and lower rolls are journaled and faces of the rails are grooved, as indicated at 28, to form guides for vertical movement of the bearing blocks therein. late 29-is seated on the bearings 26 and a screw 30 having an operating wheel 31 is mounted in a bar 32 and is adapted tobear on the middle portion of the spring bar 29 and cause it to exert a yielding pressure on the bearings of the upper roll, resisting separation of the rollers when the clothes are inserted between them. This bar 32'is pivoted at 33 at one end between the rails and is' movement by slots 37 and screws 38. A lever 39 is pivoted at 40 and'has a lug 39 in engagement with the plate 34 for the purpose of retracting it and releasing the plate from its locking slot 35' in the plate 35. When this lever is depressed, the bar 32 is released and may be raised to release the pressure of the wringer rolls. Plates 41 are secured to the inner faces of the rails and are provided with flanges 41' which encircle the ends of the rollers and prevent the clothes from working out beyond the ends of the rollers A spring and becoming tangled between them and the rails. These plates and the flanges thereon also serve as water drains, Water-inwardly upon the board beneath the wringer rolls.

A plate 42 is preferably provided, secured to the outer face of the upright rails 5 and covering the bearings for the rollers and the ends of the roller shafts. Bars 43 are secured to the upright rails 5 and extend between them on opposite sides of the lower roller 16 directing the easily and quickly tightened.

v A wringer board 47 has rollers 48 at its upper and lower edges and is provided with a flange 49 on its under side having a longitudinal recess 50 therein to receive a tie rod 51 that is secured at its ends in the blocks 25 and extends lengthwise of the wringer frame, the board 47 having a limited sliding movement on this rod.

The sides of the board 47 have flanges 52 provided with longitudinal notches 53 and the hooks 54 and 54 are pivoted on the rails 5 and adapted to enter these notches I and lock the board in its adjusted position.

This board is free to tilt toward either side of the wringer and when so tilted, one or the other of the hooks 54 and 54* will be in position to enter-the recess 53 and temporarily lock the board in its tilted position.

When the board is tilted to a horizontal position, it may be easily and quickly disengaged from the wringer for cleaning purposes or'for the purpose of allowing the wringer to be compactly packed and shipped. When the board is in use and tilted to one side or the other, it will be securely locked beneath the rolls in the manner described.

.This wringer frame is composed of comparatively few parts. It is of strong and durable construction, means'bein provided for connectin it with the housmg of the drive and rigldly supporting it thereon.

I claim as my invention:

, 1. A wringer frame comprising end rails and rollers journaledtherein having driving connections between them. a housing secured to the one end of the wringer frame and enclosing said driving connections, a drive shaft housing having its upper portion pivotally connected to said wringer frame housing and a rod connected with the lower portion of said wringer frame housing and adjustably connected with the lower portion of said drive shaft housing.

2.A wringer frame comprising end rails and rollers journaled therein, a housing mounted on one end of said frame, cross bars secured to said rails upon each side thereof, and diagonal-brace rods connected to said housing at one end and having their opposite ends seated in said cross bars.

3. A wringer frame comprising end rails, upper and lower rollers journ'aled therein,

a drive shaft housing having its upper portion pivotally supported by said wringer frame, and means adjustably connecting the lower portion of said wringer frame with the corresponding portion of said housing.

4. A wringer frame comprising end rails, upper and lower rollers journaled therein, a drive shaft having driving connections with said rollers, a housing for said drive shaft, a pivoted connection for said housing with said frame on one side of said driving connections, and an adjustable connection between said housing and frame on the other side of said driving connection.

5. A clothes wringer comprising end rails and a middle portion between said rails, upper and lower wringer rolls mounted in said rails, a driving mechanism housing having means for connection with one of said rolls, and means above and below said connection pivotally connecting said housing with said wringer frame and permitting the adjustment of said housing for alignment of its driving connection with said roll.

6. A wringer frame comprising end rails and rollers journaled therein, having driving connections between them, a housing secured to one end of said wringer frame and enclosing said driving connections, a drive shaft housing having its upper portion pivotally connected to said wringer frame housing, and means adjustably connecting the lower portion of said wringer frame housing with the corresponding portion of said drive shaft housing.

7. A wringer frame comprising end rails and a horizontal bar between them, upper and lower wringer rolls mounted in said rails, lugs projecting outwardly from one of said rails, a driving mechanism housing and a bolt passing through said lugs and through the upper portion of said housing and forming a pivotal connection between said rail and housing, and means adjustably connecting the lower portion of said rail with said housing.

8. A clothes wringer comprising end rails and a connecting bar between them, upper and lower wringer rolls mounted in said rails, lugs projecting outwardly from one of said rails, a driving mechanism housing and a bolt passing through said lugs and through the upper portion of said housing and forming a pivotal connection, lugs depending from the lower portion of the same rail, a bolt passing through said last-named lugs, and a tie-rod pivoted on said bolt at one end and adjustably connected with said housing at its other end.

In witness whereof, I have hereunto set my hand this 9th day of May1921.

ARTHUR O. HUBBARD.
